Graph:

Plot the points.

Connect the points with a smooth curve.

$\"\"$

Graph the function: $\"\"$ .

$\"\"$

Observe the graphs:

The two graphs are equal.

$\"\"$

(b) The integral is $\"\"$ .

$\"\"$

The value of $\"\"$ .

(a)

$\"\"$

Observe the graph:

The curve with plotted points and graph of $\"\"$ are equivalent.

(b)

Graph the functions: $\"\"$ on $\"\"$ and $\"\"$ .

$\"\"$

Observe the graphs:

Graph of $\"\"$ on $\"\"$ and $\"\"$ are equivalent.
